OVEN DOO PATENT OFFICE EVANSVILLE, INDIANA, ASSTGNOR TO HOOSIER LAMP AND STAMP- ING CORPORATION, OF. EVANSVILLE, INDIANA Application filed June 6, 1928. Serial No. 283,418.

This invention relates to oven doors for domestic cooking stoves.

My object is to provide oven doors of 1mroved construction combined with a door 5 rame in an improved manner'whereby the constructionis cheaper and easier to manufacture and may be entirely made of stamped material and angle iron wlthout resorting to castings and whereby the parts may be more readily assembled or taken apart and will be strong, durable, and eflicient.

Modern gas ranges are usually provided with ovens arranged one above the other and I have shown and described the invention as rovided for upper and lower ovens. It is to understood, however, that insofar as the door construction and its co-operation with the the frame on the front of the range or stove is concerned, the invention is not limited to embodiment in a pair of doors as the features thereof may be provided in a single door. One of the objects of the invention is to provide the door and its backing or lining with flanges and a channel whereby the two are secured together without resort having to be had to fastening means or bolts other than those which attach the handle to the door, thus simplifyingand cheapening the construction in that respect and facilitating assembly and separation of said parts.

Another object is to provide improved means for hingin an oven door, embodying a single hinge ro which may eitherbe provided with a nut or be directly screwed into the door frame and which co-ope'rates with a channel and flange on the back or lining clear across the width of the door thereby equalizing the pressure on the joint all the way across the door and afl'ording a simple, strong, easily assembled and taken apart hinge.

A further object is to provide bracing channel irons for the door to strengthen it and prevent it from flexing or warping and, in combination therewith, to provide guiding hinges received in the vertical ones of the channel irons, thus affordin a long and secure connection for the guid ng hinges, such hinges operating through slots in the door frame and being subject to the usual spring tensioning means.

of similar construction.

Another object is to provide an improved combination of door frame and doors, whereby lightness is achieved, the vertical height of the door frame is lowered and interference of the doors with each other which would tend to chip the enamel, is prevented.

In a divisional" application 'Serial No. 419,680, filed January 9, 1930, I have set forth and claimed an improved friction catch.

A practical embodiment of the invention is hereinafter. described and shown in the accompanying drawings, in which:

Figure l, is a front elevation, both doors being closed;

Fig. 2, is a rear elevation, both doors being close Figs. 3 and 4, are opposite end elevations;

. Fig. 5, is a view looking toward the inside of the back, showing the channel irons, the flange, and the connections for the guiding hinges; and

6, is a detail section on the line 66,

The frame 1 by which the doors are attached to the front of the range or stove is of U shape, being of angle iron construction. If upper and lower doors be provided, as shown, a light angle iron cross piece 2 is riveted to the legs'of the frame 1 and serves as a stop for the upper part of the lower door. This cross piece is for the purpose of bracing the frame ,1 and serving as a support for the front end of the burner hanger.- The burner will also be supported at the rear of the oven. The cross piece serves as a closure to prevent a crack existing between the lower edge of the upper door and the upper edge of the lower door, which would let heat escape.

The doors, shown generally at 3 and 4, are

Each door comprises a door proper or front 3, 4, and a back or lining, the respective linings for the doors 3 and 4 appearing at 5 and 6. To prevent buckling, flexing, or warping of the linings 5, 6, they are provided with vertical channel irons 7 adjacent the flanges 8 at their sides.

It will be understood that each lining has a continuous flange 8 which fits within a corresponding continuous flange 9 on the door.

As shown in Fig. 6, that part of the flange 9 which extends across the bottom of the door is provided with a lip or extension 10 extending clear across the lower edge of the door, thereby providing a channel 11.

The lower edge of the lining where the lower part of the flange extends thereacross, is slightly oflset as shown at 12, Fig. 6, and is received inside of, and against, the flange or lip 10. This construction entirely eliminates bolts for securing the lining to the door except the bolts which secure the handle. The respective handles appear at 13 and 14:, said handles being of the usual type and secured by nuts 15 on the screws 16 which project from the handles and pass through holes in the door and its lining.

It will be understood that inasmuch as the lower edge of the lining is interlocked with the lip, as shown in Fig. 6 and for the reason that the lining telescopes within the back of the door, the fastenings for the handle are the only ones required to secure the lining to the door.

The vertical irons 7 may be secured to the '5 linings 5, 6 in any manner, but riveting, as

shown at 17 constitutes a convenient means for that purpose.

There is another channel iron 7 extending across the upper part of the lining and secured by suitable fastenings such as rivets 17.

Each lining carries guide hinges 18 which have elongated straps or extensions 19 integral therewith that lie in the channel irons 7 and are secured thereto by certain ones of the rivets 17 thus affording a very rigid connection for the guiding hinges. The guiding hinges project through slots in the channel irons 7 and through slots 20 in the linings and slots 21 in the frame 1, thereby preventing lateral movement of the doors.

Spring means such as 22, 23 co-operating with the iding hinges 18, serve the usua purpose 0 restoring the doors to closed position.

The doors are hinged on stifl rods 24 spanning the frame 1 and provided with suitable means at their ends for securing them to the frame 1. As shown, these rods have a head 25 at one end and a removable nut 26 at the other end but, instead of a nut, the end of the rod could be screwed into the frame 1. The hinge rods 24 lie in the channels 11 and while said rods are not directly connected to either the door or its lining, nevertheless they serve as hinging means for the doors, allowing the doors to operate and receive pressure equally for the full len h thereof, said rods being adapted to be rea ily inserted and removed and simplifying and cheapening that part of the construction.

The catches for the doors comprise the spring pieces 27, respectively secured by screw bolts 28 to the frame 1 and cross-piece 2 and are adapted to pass through slots 29 in the linings 5, 6 and to engage inclined,

struck-up, keepers 30 on the linings. Thus, when the catch and its keeper are engaged, such engagement occurs on the inside of the door, that is, between the door and its lining. The foregoing catch is claimed in a divisional application Serial N 0. 419,680, filed January 9, 1930.

What I claim is:

1. The combination with an oven door provided with a lining or backing, said door and backing collectively being provided with a channel located between them which extends from side to side thereof, of a removable rod lying in said channel, and a frame which carries said rod.

2. The combination with an oven door provided on its inner face with channel irons, of guiding hinges provided with extensions which are disposed within the aforesaid channel irons and are secured thereto.

3. The combination with an oven door provided on its inner face with channel irons, of guiding hinges provided with extensions which are disposed within the aforesaid channel irons and are secured thereto, said guiding hinges extending through the door and being located on the inside thereof, and a frame having openings through which said guiding hinges extend. I

4. The combination with an oven door, and a lining for its inner face, of reinforcements carried by the lining, guiding hinges for said door which are connected to the reinforcements and provided with elongated parts, said guiding hinges extending through the reinforcements, the lining, and the oven door, and a frame which mounts said door and has openings through which said guiding hinges project.

In testimony whereof I afiix my signature.

WALTER MOLL.
